Triazole compounds and methods of making same

ABSTRACT

The present invention relates to novel triazole compounds of the following formula:                    
     wherein R 1  to R 5  have the meanings provided herein. The invention further relates to combinatorial libraries containing two or more such compounds, as well as methods of preparing triazole compounds.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the synthesis of compounds comprising heterocyclic rings. In one specific embodiment, the invention provides novel triazoles as well as novel combinatorial libraries comprised of such compounds.

2. BACKGROUND INFORMATION

The process of discovering new therapeutically active compounds for a given indication involves the screening of all compounds from available compound collections. From the compounds tested, one or more structures is selected as promising lead. A large number of related analogs are then synthesized in order to develop a structure-activity relationship and select one or more optimal compounds. With traditional “one-at-a-time” synthesis and biological testing of analogs, this optimization process is long and labor intensive. Adding significant numbers of new structures to the compound collections used in the initial screening step of the discovery and optimization process cannot be accomplished with traditional “one-at-a-time” synthesis methods, except over a time frame of years or even decades. Faster methods are needed what allow for the preparation of up to thousands of related compounds in a matter of days or a few weeks. This need is particularly evident when it comes to synthesizing more complex compounds, such as triazoles.

Combinatorial approaches have recently been extended to “organic,” or non-peptide, libraries. Zambias et al. (U.S. Pat. No. 5,712,171) describe a method of generating libraries that contain aminimides, oxazolones, sulfonylaminides and phosphonylaminides as the core structure in spatially arranged arrays. Combinatorial chemical methods have been applied to a limited number of heterocyclic compounds, as described, for example, in Wilson et al., Molecular Diversity, 3:95-112 (1998); U.S. Pat. Nos. 5,288,514; 5,324,483; and Goff et al., J. Org. Chem., 60:5748-5749 (1995). See also U.S. Pat. Nos. 5,549,974 and 5,506,337. However, the heterocyclic libraries to date contain compounds of limited diversity and complexity.

Substituent limitations have been overcome for mixtures of peptides and peptidomimetics through the use of solid phase techniques versus solution-phase. An important step in the development of solid-phase techniques was the discovery of methods to prepare large numbers of individual compounds simultaneously, as described, for example, by Houghten in U.S. Pat. No. 4,631,211. These solid phase methods, however, have rarely been applied to the syntheses of complex heterocyclic structures. Therefore a need exists to develop more complex “organic” libraries based on heterocyclic medicinal compounds which would need less time and effort in the synthesis and testing required to bring an organic pharmacetical product to fruition. In short, improved methods for generating therapeutically useful heterocyclic compounds, such as triazole derivatives, are desired.

Triazole compounds have been the subject of investigation in a number of different biological areas. For example, triazole derivatives have been proposed as useful: (a) as benzodiazepine receptor agonists (Francis et al., J. Med. Chem., 34:281-290 (1991); (b) in treating cardiovascular disorders (U.S. Pat. No. 5,098,920); (c) as fungicides and plant-growth regulators (U.S. Pat. No. 4,598,085); (d) as insecticides (U.S. Pat. No. 5,756,522) (e) in treating allergies; (f) in treating hypertension (U.S. Pat. No. 4,338,453); and (g) as angiotensin antagonists (U.S. Pat. No. 5,281,614). However, more complex triazole derivatives, especially with substitutions at the 1 and 2 nitrogen positions, have been difficult to attain.

This invention satisfies this need and provides related advantages as well. The present invention overcomes the known limitations to classical serial organic synthesis of triazole derivatives, for example, as well as the shortcomings of combinatorial chemistry related to triazole compounds. The present invention allows for rapid generation of large diverse libraries of complex triazoles as discrete molecules or molecules bound to solid support, such as a resin. The present invention can utilize a readily available pool of building blocks that can be incorporated into the various regions of the molecule. Furthermore, the method of making the present invention allows for the use of building blocks that contain a wide range of diverse functionality. Therefore, building blocks, such as those described above, can provide libraries that consist of large numbers as well as libraries that are extremely diverse with respect to the functionality contained within those libraries. The present invention combines the techniques of solid-phase synthesis of triazoles and the general techniques of synthesis of combinatorial libraries to prepare highly diverse new triazole compounds.

The invention also provides methods for making triazole compounds and libraries. In one method of the invention, triazole compounds can be prepared by (a) coupling a hydroxy ester to a solid support, such as a resin via the hydroxy moiety (see FIG. 1); (b) transforming the ester moiety to an acyl hydrazine by reacting the ester with a hydrazino compound (see FIG. 2); and (c) forming the triazole ring compound by reacting the acyl hydrazine with an amidino compound (see FIG. 3).

Another method further includes reacting the resin bound triazole compound with an electrophile. Such an electrophile can include an alcohol, aldehyde or an alkyl substituted with one or more halides (see FIG. 4).

When the electrophile contains an alcohol moiety, the resulting triazole alcohol compound can be further reacted with a sulfonyl compound to form a triazole sulfonyl compound (see FIG. 4).

An additional method of making triazole compounds and libraries further includes aminating the triazole compound (see FIG. 5). Other methods further include (a) acylating the amino portion of the amino triazole compound; (b) sulfonating the amino portion of the amino triazole compound; (c) reacting the amino portion of the amino triazole compound with an isocyanate compound; or (d) reductively alkylating the amino portion of the amino triazole compound (see FIG. 6).

When the above-described compounds include one or more chiral centers, the stereochemistry of such chiral centers can independently be in the R or S configuration, or a mixture of the two. The chiral centers can be further designated as R or S or R,S or d,D, l,L or d,l, D,L.

Thus, these compounds may crystallize with, for example, waters of hydration, or one, a number of, or any fraction thereof of molecules of the mother liquor solvent. The solvates and hydrates of such compounds are included within the scope of this invention.

One or more compounds of the invention, even when in a library, can be in the biologically active ester form, such as the non-toxic, metabolically-labile ester-form.

Such non-naturally-occurring amino acids include, for example, norleucine (“Nle”), norvaline (“Nva”), L- or D-naphthalanine, ornithine (“Orn”), homoarginine (homoArg) and others well known in the peptide art, such as those described in M. Bodanzsky, “Principles of Peptide Synthesis,” 1st and 2nd revised ed., Springer-Verlag, New York, N.Y., 1984 and 1993, and Stewart and Young, “Solid Phase Peptide Synthesis,” 2nd ed., Pierce Chemical Co., Rockford, Ill., 1984, both of which are incorporated herein by reference. Amino acids and amino acid analogs can be purchased commercially (Sigma Chemical Co.; Advanced Chemtech) or synthesized using methods known in the art.

The term “functionalized resin” means any resin, crosslinked or otherwise, where functional groups have been introduced into the resin, as is common in the art. Such resins include, for example, those functionalized with amino, alkylhalo, formyl or hydroxy groups. Such resins which can serve as solid supports are well known in the art and include, for example, 4-methylbenzhydrylamine-copoly(styrene-1% divinylbenzene) (MBHA), 4-hydroxymethylphenoxymethyl-copoly(styrene-1% divinylbenzene), 4-oxymethyl-phenyl-acetamido-copoly(stryene-1% divinylbenzene)(Wang), 4-(oxymethyl)-phenylacetamido methyl (Pam), and Tentagel™, from Rapp Polymere Gmbh, trialkoxy-diphenyl-methyl ester-copoly(styrene-1% divinylbenzene)(RINK) all of which are commercially available. Other functionalized resins are known in the art and can be use without departure from the scope of the current invention. Such resins may include those described in Jung, G., Combinatorial Peptide and Nonpeptide Libraries, A Handbook (VCH Verlag, 1996) or Bunin, B. A., The Combinatorial Index (Academic Press, 1998) and are incorporated herein by reference.

As used herein, a “combinatorial library” is an intentionally created collection of differing molecules which can be prepared by the means provided below or otherwise and screened for biological activity in a variety of formats (e.g., libraries of soluble molecules, libraries of compounds attached to resin beads, silica chips or other solid supports). A “combinatorial library,” as defined above, involves successive rounds of chemical syntheses based on a common starting structure. The combinatorial libraries can be screened in any variety of assays, such as those detailed below as well as others useful for assessing their biological activity. The combinatorial libraries will generally have at least one active compound and are generally prepared such that the compounds are in equimolar quantities.

Compounds disclosed in previous work that are not disclosed as part of a collection of compounds or not disclosed as intended for use as part of such a collection are not part of a “combinatorial library” of the invention. In addition, compounds that are in an unintentional or undesired mixture are not part of a “combinatorial library” of the invention.

A combinatorial library of the invention can contain two or more of the above-described compounds. The invention further provides a combinatorial library containing three, four or five or more of the above-described compounds. In another embodiment of the invention, a combinatorial library can contain ten or more of the above-described compounds. In yet another embodiment of the invention, a combinatorial library can contain fifty or more of the above-described compounds. If desired, a combinatorial library of the invention can contain 100,000 or more, or even 1,000,000 or more, of the above-described compounds.

By way of example, the preparation of the combinatorial libraries can use the “split resin approach.” The split resin approach is described by, for example, U.S. Pat. No. 5,010,175 to Rutter, WO PCT 91/19735 to Simon, and Gallop et al., J. Med. Chem., 37:1233-1251 (1994), all of which are incorporated herein by reference.

The amino acids are indicated herein by either their full name or by the commonly known three letter code. Further, in the naming of amino acids, “D-” designates an amino acid having the “D” configuration, as opposed to the naturally occurring L-amino acids. Where no specific configuration is indicated, one skilled in the art would understand the amino acid to be an L-amino acid. The amino acids can, however, also be in racemic mixtures of the D- and L-configuration or the D-amino acid can readily be substituted for that in the L-configuration.

For preparing pharmaceutical compositions containing compounds of the invention, inert, pharmaceutically acceptable carriers are used. The pharmaceutical carrier can be either solid or liquid. Solid form preparations include, for example, powders, tablets, dispersible granules, capsules, cachets, and suppositories.

A solid carrier can be one or more substances which can also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, or tablet disintegrating agents; it can also be an encapsulating material.

In powders, the carrier is generally a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active compound is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.

For preparing pharmaceutical composition in the form of suppositories, a low-melting wax such as a mixture of fatty acid glycerides and cocoa butter is first melted and the active ingredient is dispersed therein by, for example, stirring. The molten homogeneous mixture is then poured into convenient-sized molds and allowed to cool and solidify.

Powders and tablets preferably contain between about 5% to about 70% by weight of the active ingredient. Suitable carriers include, for example, magnesium carbonate, magnesium stearate, talc, lactose, sugar, pectin, dextrin, starch, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, a low-melting wax, cocoa butter and the like.

The pharmaceutical compositions can include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component (with or without other carriers) is surrounded by a carrier, which is thus in association with it. In a similar manner, cachets are also included. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration.

Liquid pharmaceutical compositions include, for example solutions suitable for oral or parenteral administration, or suspensions, and emulsions suitable for oral administration. Sterile water solutions of the active component or sterile solutions of the active component in solvents comprising water, ethanol, or propylene glycol are examples of liquid compositions suitable for parenteral administration.

Sterile solutions can be prepared by dissolving the active component in the desired solvent system, and then passing the resulting solution through a membrane filter to sterilize it or, alternatively, by dissolving the sterile compound in a previously sterilized solvent under sterile conditions.

Aqueous solutions for oral administration can be prepared by dissolving the active compound in water and adding suitable flavorants, coloring agents, stabilizers, and thickening agents as desired. Aqueous suspensions for oral use can be made by dispersing the finely divided active component in water together with a viscous material such as natural or synthetic gums, resins, methyl cellulose, sodium carboxymethyl cellulose, and other suspending agents known to the pharmaceutical formulation art.

Preferably, the pharmaceutical composition is in unit dosage form. In such form, the composition is divided into unit doses containing appropriate quantities of the active triazole. The unit dosage form can be a packaged preparation, the package containing discrete quantities of the preparation, for example, packeted tablets, capsules, and powders in vials or ampules. The unit dosage form can also be a capsule, cachet, or tablet itself, or it can be the appropriate number of any of these packaged forms.

As pharmaceutical compositions for treating infections, pain, or any other indication the compounds of the present invention are generally in a pharmaceutical composition so as to be administered to a subject at dosage levels of from 0.7 to 7000 mg per day, and preferably 1 to 500 mg per day, for a normal human adult of approximately 70 kg of body weight, this translates into a dosage of from 0.01 to 100 mg/kg of body weight per day. The specific dosages employed, however, can be varied depending upon the requirements of the patient, the severity of the condition being treated, and the activity of the compound being employed. The determination of optimum dosages for a particular situation is within the skill of the art.

The compounds of and combinatorial libraries containing the same can be prepared as set forth in FIGS. 1 to 6 and described below.

Variant triazole combinatorial libraries can be prepared in order to achieve a high level of diversity. For instance, a variety of hydroxyl esters can be attached to solid support by a range of methods (see FIG. 1 and Example 1). More specifically, phenols with an ester moiety were loaded to Wang resin via Mitsunobu reaction, or to Bromo Wang resin by substitution reaction. Aliphatic alcohols with an ester moiety were similarly loaded to Bromo Wang or Wang trichloroacetimidate resin (see Hanessian and Xie, Tetrahedron Letters, 39:733-736 (1998), which is incorporated herein by reference).

Other esters can be loaded to a solid support in various alternate ways. For example, a cleavable amino resin can be reacted with haloalkylesters, or by coupling the carboxylic acid group of diacid monoesters to a resin-bound amine via an amide bond (e.g., methylbenzhydrylamine (MBHA)).

The resulting resin-bound ester can then be transformed to an acyl hydrazine (see FIG. 2 and Example 2). The acyl hydrazine can then be cyclized into a triazole by a range of methods(see FIG. 3 and Example 3).

The triazole can then be reacted with an electrophile. Such an electrophile can include one containing a range of moieties such as any one of a variety of alcohols, aldehydes or alkyls substituted with one or more halides. When the electrophile is an alcohol, the resulting triazole-alcohol can be transformed into the corresponding mesylate. See FIG. 4 and Example 4.

The mesylate, halide or triazole-aldehyde made by the previous reaction can then be aminated using one of a variety of amines. See FIG. 5 and Example 5. The reulting amino-triazolo can then be further derivatized, for example, by acylation (using one of a variety of carboxylic acids; see Example 8), sulfonation (using one of a variety of sulfonyl halides; see Example 9), by reacting with one of a variety of isocyanates (see Example 10) or by reductive alkylation (see Example 11). See also FIG. 6 and Example 6.

Resin-bound triazoles can be cleaved from the resins by treating them with trifluoroacetic acid (TFA)/DCM solution. After extraction and lyophilization, non-support bound triazole compounds can be obtained. See Example 12.

Triazole compounds and libraries, such as those of the present invention, can be made utilizing individual polyethylene bags, referred to as “tea bags” (see Houghten et al., Proc. Natl. Acad. Sci. USA 82: 5131 (1985); Biochemistry, 32:11035 (1993); and U.S. Pat. No. 4,631,211, all of which are incorporated herein by reference).

The nonsupport-bound combinatorial libraries can be screened as single compounds. In addition, the nonsupport-bound combinatorial libraries can be screened as mixtures in solution in assays such as radio-receptor inhibition assays, anti-bacterial assays, anti-fungal assays, calmodulin-dekpendent phosphodiosterase (CaMPDE) assays and phosphodiesterase (PDE) assays, as described in detail below. Deconvolution of highly active mixtures can then be carried out by iterative or positional scanning methods. These techniques, the iterative approach or the positional scanning approach, can be utilized for finding other active compounds within the combinatorial libraries of the present invention using any one of the below-described assays or others well known in the art.

The iterative approach is well-known and is set forth in general in Houghten et al., Nature, 354, 84-86 (1991) and Dooley et al., Science, 266, 2019-2022 (1994), both of which are incorporated herein by reference. In the iterative approach, for example, sub-libraries of a molecule having three variable groups are made wherein the first variable is defined. Each of the compounds with the defined variable group is reacted with all of the other possibilities at the other two variable groups. These sub-libraries are each tested to define the identity of the second variable in the sub-library having the highest activity in the screen of choice. A new sub-library with the first two variable positions defined is reacted again with all the other possibilities at the remaining undefined variable position. As before, the identity of the third variable position in the sub-library having the highest activity is determined. If more variables exist, this process is repeated for all variables, yielding the compound with each variable contributing to the highest desired activity in the screening process. Promising compounds from this process can then be synthesized on larger scale in traditional single-compound synthetic methods for further biological investigation.

The positional-scanning approach has been described for various combinatorial libraries as described, for example, in R. Houghten et al. PCT/US91/08694 and U.S. Pat. No. 5,556,762, both of which are incorporated herein by reference. In the positional scanning approach, sublibraries are made defining only one variable with each set of sublibraries and all possible sublibraries with each single variable defined (and all other possibilities at all of the other variable positions), made and tested. From the instant description one skilled in the art could synthesize combinatorial libraries wherein two fixed positions are defined at a time. From the testing of each single-variable defined combinatorial library, the optimum substituent at that position can be determined, pointing to the optimum or at least a series of compounds having a maximum of the desired biological activity. Thus, the number of sublibraries for compounds with a single position defined will be the number of different substituents desired at that position, and the number of all the compounds in each sublibrary will be the product of the number of substituents at each of the other variables.

Individual compounds and pharmaceutical compositions containing the compounds, as well as methods of using the same, are included within the scope of the present invention. The compounds of the present invention can be used for a variety of purposes and indications and as medicaments for any such purposes and indications. For example, as described above, triazole compounds of the present invention can be used as pesticides, acaricides, receptor agonists or antagonists and antimicrobial agents, including antibacterial or antiviral agents. Additionally, the subject compounds can be useful as analgesics. Assays which can be used to test the biological activity of the instant compounds include antimicrobial assays, a competitive enzyme-linked immunoabsorbent assay and radio-receptor assays, as described below.

The ability of the compounds to inhibit bacterial growth, and therefore be useful to that infection, can be determined by methods well known in the art. Compounds of the present invention were shown to have antimicrobial activity by the in vitro antimicrobial activity assay described below and, therefore, are useful as antimicrobial agents.

In addition, an exemplary in vitro antimicrobial activity assay is described in Blondelle and Houghten, Biochemistry 30:4671-4678 (1991), which is incorporated herein by reference. In brief, Staphylococcus aureus ATCC 29213 (Rockville, Md.) is grown overnight at 37° C. in Mueller-Hinton broth, then re-inoculated and incubated at 37° C. to reach the exponential phase of bacterial growth (i.e., a final bacterial suspension containing 10⁵ to 5×10⁵ colony-forming units/ml). The concentration of cells is established by plating 100 μl of the culture solution using serial dilutions (e.g., 10⁻², 10⁻³ and 10⁻⁴) onto solid agar lates. In 96-well tissue culture plates, compounds, individual or in mixtures, are added to the bacterial suspension at concentrations derived from serial two-fold dilutions ranging from 1500 to 2.9 μl. The plates are incubated overnight at 37° C. and the growth determined at each concentration by OD₆₂₀ nm. The IC₅₀ (the concentration necessary to inhibit 50% of the growth of the bacteria) can then be calculated.

The competitive ELISA method which can be used here is a modification of the direct ELISA technique described previously in Appel et al., J. Immunol. 144:976-983 (1990), which is incorporated herein by reference. It differs only in the MAb addition step. Briefly, multi-well microplates are coated with the antigenic peptide (Ac-GASPYPNLSNQQT-NH₂) at a concentration of 100 pmol/50 μl. After blocking, 25 μl of a 1.0 mg/ml solution of each mixture of a synthetic combinatorial library (or individual compound) is added, followed by MAb 125-10F3 (Appel et al., supra) (25 μl per well). The MAb is added at a fixed dilution in which the bicyclic guanidine in solution effectively competes for MAb binding with the antigenic peptide adsorbed to the plate. The remaining steps are the same as for direct ELISA. The concentration of compound necessary to inhibit 50% of the MAb binding to the control peptide on the plate (IC₅₀) is determined by serial dilutions of the compound.

Alternative screening can be done with radio-receptor assays. The radio-receptor assay, can be selective for any one of the μ, κ, or δ opiate receptors. Compounds of the present invention can be useful in vitro for the diagnosis of relevant opioid receptor subtypes, such as κ, in the brain and other tissue samples. Similarly, the compounds can be used in vivo diagnostically to localize opioid receptor subtypes.

The radio-receptor assays are also an indication of the compounds' analgesic properties as described, for example, in Dooley et al., Proc. Natl. Acad. Sci., 90:10811-10815 (1993). For example, it can be envisioned that these compounds can be used for therapeutic purposes to block the peripheral effects Of a centrally acting pain killer. For instance, morphine is a centrally acting pain killer. Morphine, however, has a number of deleterious effects in the periphery which are not required for the desired analgesic effects, such as constipation and pruritus (itching). While it is known that the many compounds do not readily cross the blood-brain barrier and, therefore, elicit no central effect, the subject compounds can have value in blocking the periphery effects of morphine, such as constipation and pruritus. Accordingly, the subject compounds can also be useful as drugs, namely as analgesics, or to treat pathologies associated with other compounds which interact with the opioid receptor system.

Additionally, such compounds can be tested in a σ receptor assay. Ligands for the σ receptor can be useful as antipsychotic agents, as described in Abou-Gharbia et al., Annual Reports in Medicinal Chemistry, 28:1-10 (1993).

Radio-receptor assays can be performed with particulate membranes prepared using a modification of the method described in Pasternak et al., Mol. Pharmacol. 11:340-351 (1975), which is incorporated herein by reference. Rat brains frozen in liquid nitrogen can be obtained from Rockland (Gilbertsville, Pa.). The brains are thawed, the cerebella removed and the remaining tissue weighed. Each brain is individually homogenized in 40 ml Tris-HCl buffer (50 mM, pH 7.4, 4° C.) and centrifuged (Sorvall® RC5C SA-600: Du Pont, Wilmington, Del.) (16,000 rpm) for 10 minutes. The pellets are resuspended in fresh Tris-HCl buffer and incubated at 37° C. for 40 minutes. Following incubation, the suspensions are centrifuged as before, the resulting pellets resuspended in 100 volumes of Tris buffer and the suspensions combined. Membrane suspensions are prepared and used in the same day. Protein content of the crude homogenates generally range from 0.15-0.2 mg/ml as determined using the method described in Bradford, M. M., Anal. Biochem. 72:248-254 (1976), which is incorporated herein by reference.

Binding assays are carried out in polypropylene tubes, each tube containing 0,5 ml of membrane suspension. 8 nM of ³H-[D-Ala²,Me-Phe⁴,Gly-ol⁵]enkephalin (DAMGO) (specific activity=36 Ci/mmol, 160,000 cpm per tube; which can be obtained from Multiple Peptide Systems, San Diego, Calif., through NIDA drug distribution program 271-90-7302) and 80 μg/ml of bicyclic guanidine, individual or as a mixture and Tris-HCl buffer in a total volume of 0.65 ml. Assay tubes are incubated for 60 mins. at 25° C. The reaction is terminated by filtration through GF-B filters on a Tomtec harvester (Orange, Conn.). The filters are subsequently washed with 6 ml of Tris-HCl buffer, 4° C. Bound radioactivity is counted on a Pharmacia Biotech Betaplate Liquid Scintillation Counter (Piscataway, N.J.) and expressed in cpm. To determine inter- and intra-assay variation, standard curves in which ³H-DAMGO is incubated in the presence of a range of concentrations of unlabeled DAMGO (0.13-3900 nM) are generally included in each plate of each assay (a 96-well format). Competitive inhibition assays are performed as above using serial dilutions of the bicyclic guanidines, individually or in mixtures. IC₅₀ values (the concentration necessary to inhibit 50% of ³H-DAMGO binding) are then calculated. IC₅₀ values of less than 1000 nM are indicative of highly active opioid compounds which bind to the p receptor, with particularly active compounds having IC₅₀ values of 100 nM or less and the most active compounds with values of less than 10 nM.

As opposed to this p receptor selective assay, which can be carried out using ³H-DAMGO as radioligand, as described above, assays selective for κ receptors can be carried out using [³H]-U69,593 (3 nM, specific activity 62 Ci/mmol) as radioligand. Assays selective for δ opiate receptors can be carried out using tritiated DSLET ([D-Ser², D-Leu⁵]-threonine-enkephalin) as radioligand. Assays selective for the σ opiate receptor can use radiolabeled pentazocine as ligand.

Screening of combinatorial libraries and compounds of the invention can be done with an anti-fungal assay. Compounds of the present invention can be useful for treating fungal infections.

Screening of combinatorial libraries and compounds of the invention also can be done with a calmodulin-dependent phosphodiesterase (CaMPDE) assay. Compounds of the present invention can be useful as calmodulin antagonists.

Calmodulin (CaM), which is the major intracellular calcium receptor, is involved in many processes that are crucial to cellular viability. In particular, calmodulin is implicated in calcium-stimulated cell proliferation. Calmodulin antagonists are, therefore, useful for treating conditions associated with increased cell proliferation, for example, cancer. In addition, calmodulin antagonists such as compounds of the subject invention are useful both in vitro and in vivo for identifying the role of calmodulin in other biological processes. The disadvantages of known antagonists such as trifluoperazine and N—(4-aminobutyl)-5-chloro-2-naphthalenesulfonamide (W13) include their non-specificity and toxicity. In contrast, advantages of the combinatorial libraries and compounds of the subject invention as calmodulin antagonists include their reduced flexibility and ability to generate broader conformational space of interactive residues as compared to their linear counterparts.

An example of an assay that identifies CaM antagonists is a CaMPDE assay. In brief, samples are mixed with 50 μl of assay buffer (360 mM Tris, 360 mM Imidazole, 45 mM Mg(CH₃COO)₂₁ pH 7.5) and 10 μl of CaCl₂ (4.5 mM) to a final volume of 251 μl. 25 μl of calmodulin stock solution (Boehringer Mannheim; 0.01 μg/μl) is then added and the samples then sit at room temperature for 10 minutes. 14 μl of PDE (Sigma; 2 Units dissolved in 4 ml of water; stock concentration: 0.0005 Units/μl) is then added, followed by 50 μl of 5′-nucleotidase (Sigma; 100 Units dissolved in 10 ml of 10 mM Tris-HCl containing 0.5 mM Mg(CH₃COO)₂, pH 7.0; stock concentration: 10 Units/ml). The samples are then incubated for 10 minutes at 30° C. 50 μl of adenosine 3′,5′-cyclic monophosphate (cAMP) (20 mM in water at pH 7.0) is added, the samples incubated for 1 hour at 30° C. and then vortexed. 200 μl of trichloroacetic acid (TCA) (55% in water) is added to a 200 μl sample aliquot, which is then vortexed and centrifuged for 10 minutes. 80 μl of the resulting supernatants of each sample is transferred to a 96-well μlate, with 2 wells each containing 80 μl of each sample. 80 μl of ammonium molybdate (1.1% in 1.1lN H₂SO₄) is then added to all the wells, and the OD of each were determined at 730 nm, with the values later subtracted to the final OD reading. 16 μl of reducing agent (6 g sodium bisulfite, 0.6 g sodium sulfite and 125 mg of 1-amino-2-naphtol-4-sulfonic acid in 50 ml of water) is then added to one of each sample duplicate and 16 μl of water is added to the other duplicate. After sitting for 1 hour at room temperature, the OD of each well is determined at 730 nm. The percent inhibition of calmodulin activity is then calculated for each sample, using as 0% inhibition a control sample containing all reagents without any test samples and as 100% inhibition a control sample containing test samples and all reagents except calmodulin. In addition, the percent inhibition of phosphodiesterase activity was determined by following a similar protocol as the CaMPDE assay described above, except not adding calmodulin to the sample mixture and calculating the percent inhibition by using as 0% inhibition a control reagent without any test samples and as 100% inhibition a control sample containing test samples and all reagents except cAMP.

EXAMPLE 12 Cleavage and Extraction

To the dry resins (in tea bags or in wells of micrometer plates) containing the triazole compounds described in the above examples, appropriate amounts of TFA/DCA solution (20 to 50% TFA) were added. The mixtures were shaken for 2-5 hours at room temperature, dried under vacuum and the resins were then extracted with either CH₃CN/H₂O (1:1) or AcOH. The extracts were lyophilized to give the cleaved triazoles and analyzed by mass spectrometry, as well as by HPLC equipped with a UV detector and an evaporative light scattering detector (ELSD).

EXAMPLE 13 Anti-microbial Screen

Streptococcus pyogenes (ATCC# 97-03 14289) are grown in Todd Hewitt Broth (THB) (Difco Laboratories #0492-17-6) overnight until they reach an optical density of ( OD=0.636@ 570 nm) by reading 0.1 ml in a 96 well microtiter plate in a Molecular Devices Thermomax. This preparation is kept frozen as stocks in 30% v/v glycerol in 1.5 ml aliquots at −70° C. until use. Prior to screening, 1.5 ml aliquots are thawed and diluted into 50 ml THB. 200 ul of this dilution is added to 92 wells of microtiter plate. To three wells THB (200 ul) is added to serve as a blank and a sterility control. Test compounds in DMSO and appropriate concentrations of DMSO are added to Growth/Solvent Controls at 0 time. Plates are read at 0 time at 570 nm in the Molecular Devices plate reader to obtain compounds correction factors for insoluble or colored compounds. Plates are read again at 4 hrs.

Compounds are assayed at a concentration of 170 μg/ml. Percent inhibition for each compound is calculated using the following formulae:

Color correct=(O.D. 0 hr−Blank 0 hr)−(Solvent Control 0 hr−Blank 0 hr)

% Inhibition=100−(O.D.test compound 4hr−Blank 4 hr−color correct) divided by (O.D.growth/solvent control 4 hr−Blank 4 hr)
